Scientist II (Contract), Analytical Development

Join our Mission to Protect Humankind! Vaxcyte is a clinical-stage vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases, which have serious and costly health consequences when left unchecked. Working to eradicate or treat bacterial infections such as invasive pneumococcal disease, Group A Strep, and Shigella is just the beginning. Our path to success is clear and well-defined, and Vaxcyte is set up to go the distance. WHAT we do is every bit as important as HOW we do it! Our work together is guided by four enduring core values: *RETHINK CONVENTION: We bring creative and intellectual diversity to every facet of the work we do in order to innovate and re-innovate the way vaccines are delivered. *AIM HIGH: We embody our collectively audacious goal to courageously make the most complex biologics ever attempted to protect humankind. *LEAD WITH HEART: Everyone leads at Vaxcyte with a kindness-first, inclusive approach to collaboration and vigorous debate that advances our business objectives. *MODEL EXCELLENCE: The magnitude of our challenge requires our shared commitment to demonstrating integrity, accountability, equality and clarity across communications and decision making. Summary: Vaxcyte is looking for an energetic and talented individual to join our Analytical Development team. Primary responsibility for the incumbent will be to support the developmental activities currently ongoing in the laboratory as assigned. Essential Functions: • Contribute to method development, optimization, and qualification/validation readiness activities. • Design and execute experiments to evaluate critical method parameters and define appropriate system suitability and control strategies. • Troubleshoot assay and instrument performance issues using a structured approach; interpret data to identify likely root causes, implement corrective actions, and document outcomes and recommendations. • Support and/or execute method transfer activities, including protocol preparation, training support, execution at receiving labs, and resolution of transfer issues. • Support lab management and operations, including sample and inventory tracking. • Author and revise analytical methods, SOPs, protocols, and technical reports; ensure clear documentation of experimental rationale, results, and conclusions for internal review and stakeholder communication. Laboratory Operations & Instrumentation: • Coordinate routine instrument maintenance and service activities; interface with vendors and lab management team as needed and support timely issue resolution. • Ensure laboratory organization, cleanliness, and compliant material labeling/storage practices. • Manage inventory of reagents, standards, and consumables; initiate procurement, track critical supplies, and support forecasting to avoid stockouts. Team Collaboration: • Partner effectively with cross-functional teams to define analytical plans, meet project timelines, and deliver high-quality outputs. • Communicate experimental progress, data interpretation, and emerging risks clearly; propose mitigation plans and align next steps with stakeholders. • Contribute to a compliant, safety-focused, and scientifically rigorous lab culture; model good documentation practices and data integrity expectations. • Train and mentor junior staff/new team members on analytical assays, workflows, and troubleshooting; provide day-to-day technical guidance and feedback. Analytical Testing & Data Generation: • Perform routine and non-routine analytical testing using modern analytical methods (e.g., HPLC/UPLC, SEC, CE, UV-Vis, ELISA, electrophoresis, plate-based assays, and other biochemical/biophysical techniques). • Execute assays in
